Have you ever seen a Sun-Lite? The sides are hard but the top pops up 2ft, all clear vinyl windows. Their pretty unique and you open it from the inside.
Reminds me of the one I use to own. Mine was a M520 if I remember correctly. I enjoyed and used it by myself on fishing trips. Wife came along a few times and didn't care for it. She decided she wanted to camp more. That's when we bought our TT. Don't think I'ld go back to a pop up now. Probably look for a 5'er in a few years.
